A microorganism (from the Greek: μικρός‚ mikros‚ "small" and ὀργανισμός‚ organismós‚ "organism") is a microscopic organism‚ which may be a single cell[1] or multicellular organism. The study of microorganisms is called microbiology‚ a subject that began with Antonie van Leeuwenhoek’s discovery of microorganisms in 1675‚ using a microscope of his own design. Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the

The purpose of this report is to explain the process and steps used to identify a certain microorganism referred to as the unknown. Materials and Methods A test tube with an unknown microorganism will be retrieved. Once the test tube is retrieved‚ a steak for isolation will be completed in order to produce

Definition of Microorganism Microorganism (from the Greek: mikrós‚ "small" and organismós‚ "organism") is an organism that is microscopic (usually too small to be seen by the naked human eye). Microorganisms live in all parts of the biosphere where there is liquid water‚ including soil‚ hot springs‚ on the ocean floor‚ high in the atmosphere and deep inside rocks within the Earth’s crust. Microorganisms are critical to nutrient recycling in ecosystems as they act as decomposers

Title: Microorganisms are everywhere. Tara Brady Dt201 Objectives: In this experiment‚ my aim is to prove that microorganisms are present everywhere and that nowhere in our everyday lives is free from bacteria. I expect this to be the case as even germicide soaps do not kill all bacteria present on our skin; likewise household cleaning products are incapable of killing all microorganisms present. I am doing his experiment to verify the concept that microorganisms are everywhere and I most certainly

in digestion and provide vitamins. Some microbes can also be antagonistic or harmful to humans‚ and when scientists isolate them‚ they can study and identify ways on how to counteract the microbes harmful effects. This exercise aims to isolate microorganisms from a variety of environmental samples and to enumerate the different microbial species observed. Methodology Results and Discussion Bacteria‚ molds and yeast have different colony morphologies and characteristics that are specific to

Unknown Microorganism: #5 Report Callie Schalk Microbiology Professor Quave November 24‚ 2015 The unknown microorganism #5 is Pseudomonas aeruginosa. It can survive in a variety of environments and at temperatures found in clinical settings (Murray et al‚ 1999). Clinical setting is referring to temperatures such as those in the hospital environment. P. aeruginosa can also survive in aqueous environments. Pseudomonas aeruginosa is found at several different sources. Nosocomial

Unknown Experiment Introduction: The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test‚ and the very first one done‚ is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified‚ the tester has a wide array of differentiating tests at their disposal. Based on the results from these

INTRODUCTION Microorganisms such as bacteria‚ fungus‚ mold‚ and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar‚ which creates an ideal environment for the organisms to form colonies‚ which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms‚ it is necessary to use the magnification of a high-powered microscope. These techniques
